. Consider the three isotopes of magnesium discussed in Exercise 17. Given that the relative natural abundances of these isotopes are 79%, 10%, and 11%, respectively, without looking at the inside cover of this book, what is the approximate atomic molar mass of magnesium? Explain how you made your prediction.

Interpretation Introduction

Interpretation:

To explain how to determine the approximate atomic molar mass of magnesium from its isotopes and natural abundance.

Concept Introduction:

The elements having same atomic number and different mass number are known as isotopes.

Approximate atomic mass of an isotope can be calculated as average atomic mass of the given element. The average atomic mass of an element can be determined by multiplying the natural abundance of each isotope with its mass and then taking sum of each value.

Explanation

The average atomic mass of an element can be determined by multiplying the natural abundance of each isotope with its mass and then taking sum of each value.

Average atomic mass of Mg = (Mass of Mg-24 x Natural abundance of Mg-24) + (Mass of Mg-25 x Natural abundance of Mg-25) + (Mass of Mg-26 x Natural abundance of Mg-26)...
